RANSOM STITT, OF CAZENOVIA, ASSIGNOR OF ONE-HALF HIS RIGHT TO WILLIAM L. STEVENS, OF LOCK BERLIN, NEW YORK.

IMPROVEMENT l Specification forming part of Letters Patent No. May

To all whom it may concern:

Be it known that I, RANsoM Srrrr, of Gazenovia, in the county of Madison and State of N ew York, have invented a new and Valuable Improvement in Butter-Tubs; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

Figure l of the drawings is a representation of a vert-ical central section of my butter-tub and 2 is a perspective view, showing fastening device.

The nature ot' my invention consists in the construction and arrangement of a butter-tub which has for its object to keep the butter cool and excluded from the air, as will be hereinafter more fully set forth.

The annexed drawing, to which reference is made, fully illustrates my invention.

A represents a wooden tub of any suitable dimensions, and made in any of the known and usual ways. Inside of this tub A is a glass jar or vessel, B, so arranged as to leave a space all around and between the bottoms, as shown, said space being filled with a packing, C, of plaster-of-paris, or other similar nonconducting material. The glass jar or vessel B is preferably made with one or more circumferential beads, b, near the top, whereby said vessel is held more firmly in the plasterof-paris iillin g.

D is the lid of the tub, restinD on its top edge, said lid being, on-its/under side, provided with a circular rimfd, iitting inside of the tub over the filling C, and within this rim is a disk, F, of plaster-of-paris, covering the top of the interior glass vessel B. The

inner edge of the rim d is beveled, so as to hold the plaster disk F from falling out.

With this improved tub butter can be kept N BUTTER-TU BS.

205,436, dated June 25,1878; application liled 4, 187e.

for any length of time, and `also as cool as if kept in a cellar, the tub .being air-tight by means of rubber packing-rin gs a ainterposed, as shown, over the top of the glass vessel B, and between the edges of the tub and lid, and the lid fastened by devices hereinafter de' scribed. v

The plaster-of-paris is non-conductin g 5 hence the heat will not penetrate.

The glass jar cannot become strong and rancid, and will save a great deal ot time and labor in cleaning.

In the plaster-of-paris disk F I propose to use a glass cover embedded therein.

The lid D is provided with two or more fastening devices, consisting of a metal plate, G, extending downward, and having an inwardlyprojecting flange, f, at its lower end. In the sides of the tub are corresponding numbers of vertical recesses h, with a horizontal groove, i, leading from the bottom of each recess. Into these the plates G take, on the principle of the bayonet-lock, closing the lid air-tight on the tub.

What I claim as new, and desire to secure by Letters Patent, is

l. The lid D, provided with the annular rim, d, having its inner edge beveled, and with the plaster-of-paris disk F, substantially as herein set forth.

2. The combination of the tub A, glass jar B, filling C, lid D, with rim d and disk F, the Vpacking a, and fastening devices, all substantially as and for the purposes herein set forth.

In testimony that I claim the above I have hereunto subscribed my name in the presence ot' two witnesses.
